MACHINE FOR RIVING SHINGLES, &C.

Specication of Letters Patent No. 13,155, dated July 3, 1855.

To all whom zt may concern.'

Be it known that we, A. C. BILLINGS and B. H. RUGGLES, of Palmer, in thecount-v of Hampden and St-ate of l\'lassachusetts, have invented a newand Improved Machine for Cutting or Riving Shingles, Staves, &c.; and wedo hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure 1, is a verticallongitudinal section of my improvement; Fig. 2, is a horizontal sectionof ditto, (fr) Fig. 1, showing the plane of section.

Similar letters of reference indicate corresponding parts in the twofigures.

The nature of our invention consists 1st, in the peculiar means employedfor giving the necessary feed motion to the carriage and 2nd, in theemployment of ayielding or elastic head -s tock which will be fullyvdescribed hereafter.

A, Fig. 1, represents a frame constructed in any proper manner tosupport the working parts of the machine.

B, represents a transverse shaft which works in suitable bearings on thelower part of the frame A, said shaft having a toothed wheel C upon itwhich wheel gears into a pinion D, on a shaft E, which is parallel withthe shaft B, and also has upon it a fly wheel F, and driving pulley, theshaft E, being the driving shaft.

G, represents a curved lever, one end of which is connected by a bolt orpin (a) to one end of the lower partof the frame A. This lever has acurved slot (b) made through it, in which slot a pin (0) attached to oneside of the toothed wheel C, fits or works, see dotted lines Fig. 1. Theopposite end of the lever Gr, is connected by a link H, to the lowercross piece of a vertical reciprocating gate I, which works in suitableguides (d) att-ached to the frame A. To the upper part of the gate I,the knife J, is attached which is in a horizontal position, its loweredge being the cut-ting edge.

On the upper part of the frame A, there are placed two ways K, K, one ofwhich is shown in Fig. 1. Between these ways a carriage L, is fitted andworks. To the under side of the carriage a rack M, is attached asclearly shown in Fig. l. On the upper surface of the carriage L, andbetween the ways K, K, of the carriage a head stock N, works, said headstock being provided with a clamp O, at its upper end. The clamp O, maybe constructed in any proper manner and secures the block from which theshingles are cut to the vertical portion of the head stock. The headstock, considered as a whole, is formed of a hori Zontal plate (e) whichis the part which rests on the carriage L, and is fitted between theways K, K, as previously described, and a vertical part (f) to the upperend of which the clamp O, above mentioned is attached. The plate (e) ofthe head stock is attached by a spiral spring P, to the carriage L, saidspring tting in a recess in the carriage, see Fig. l. To the upper partof the frame A, underneath the carriage L, there is a lever Q, whichworks on a pivot (g) attached to a small horizontal arm (72.) on theframe, see Figs. 1 and 2. At the back part of this lever and at one endthere is a spring (i) which keeps one end of the lever against. the sideof one of the uprights (j) of the gate I. At the lower end of thisupright (j) there is attached a small inclined or wedge shapedprojection the edge of which is uppermost as shown in Fig. 1. To theopposite end of the lever Q, there is attached by a pivot (l) an arm (m)having a pawl (n), secured to its end, this pawl is kept in the teeth ofthe rack M, by a small spring (o) attached to the arm (m). The pawl (Z)has a lever (p) attached to it, the outer end of this lever projectsthrough the side of the frame A, see Fig. 2.

The operation will be readily understood. Mot-ion is given the drivingshaft E, in any proper manner, and as the toothed wheel C, rotates thepin (c) thereon in consequence of being fitted in the curved slot (b) ofthe lever G, gives said lever a vibratory movement and the gate I, isconsequently operated with a vertical reciprocating movement.

The block from which the shingles are cut represented by A', is securedto the part (f) of the head block N, by the clamp O, the grain of theblock being in a vertical position. When the gate I, has nearly reachedthe length of its upward stroke, the inclined or wedged shapedprojection (7c) will act against the end of the lever Q, and the pawlwill act against the rack M, and feed the carriage L, along so that theedge of the block will be underneath the knife J, in the gate I. Thecarriage is fed or moved a certain distance at each stroke of the gateand at a proper distance equal to the desired Width the shingle is to becut. The head block and carriage are shoved back by hand by operatingthe lever (7?) and throwing the paWl from the rack. The spring P, allowsthe head block N, and

block A, to yield or give in case of any re-V what We claim as new, anddesire to secure by Letters Patent, is

l. 7e claim giving the proper feed motion to the carriage L, by means ofthe inclined or Wedge shaped projection (7c), on the gate l, lever Q,and paWl (n) which acts against a rack on the under side of the carriageL, as herein shown and described.

2. We claim connecting or attaching the head block N, to the carriage L,by lneans of the spiral spring P, for the purpose of allowing the headblock to yield or give when necessary as herein set forth.
